concave at this place; instead of this arrangement, however, itanight be provided at this place with small ribs into which the material of the disk "o enters when being shrunk on. Instead of shrinking the disk o on the axle it may be pressed on cold, in which case, of course, there is no special shape at this place of the z xle. The disk o prevents the loose wheel c sliding oil' the axle and is so arranged that there is only a minimum amount of clearance or play between the hub of the wheels and the inner parts of the lubricating box. lt a wheel or a bearing has to be exchanged the disk o can be readily wrenched off, lOwing to the one wheel being attached by shrinking or pressing it on the axle and to the closure disk being likewise attached by shrinking or pressing it on the other end We provide that the parts or members which are intended to remain firmly connected with the axle do not become loose in the course of time and even when subjected to rough usage.

It it is desired that the pair of wheels and axle shall not be dismernbered by wrenching off the described end disk or ring the latter may be pushed on to the end of the axle and secured by a split pin, cotter, key or bayonet joint, or it may be screwed and locked thereon.. Fig. 5 shows an einbodiment in which the disk or ring o is placed loose on the end of the axle and secured by a Cotter or key p.
